For now, I'll run it as is, and if it does come apart, then figure out how to keep them together, without resorting to super glue :p

Instead of superglue what about hot glue.

I'd try Teflon thread seal tape, the type that you use to stop water leaking out of connectors in pipes. It only sticks to itself so won't do any permanent changes and its not going to be affected by the temperatures we get to. I love it! Otherwise I can also recommend dental floss. I use both of these in my day job as a Low Temperature physicist and can vouch for their performance below 1 mK. :D

shoogoo should also do a a good job holding it together and can be removed pretty easy.

The old standby has always been heat shrink tubing. You can get it in any size you want if you look around. Some LHS used to carry bigger sizes to cover sub-c cells and complete packs.

gap is the best for cooling temps by enough air room
for the bottom fet that has no heatsink
that should not reduced

The top pcb is quite heavier than the bottom pcb,
if this can be inverted
it will also great for Low CG, but requires new Heatsink
like teamwave heatsink have it cools the bottom wafer.

Timing Sensor
 
I have 17.5 V3 speedpassion...my Timing sensor plug in the motor got damaged..
Question about the V3 speedpassion motor sensor,17.5 are the same sensor as others? Will the mod V3 sensor works in my 17.5motor ?

Any one tryet 2,0 gt LP speedo in 1:12 scale and witch software is the best for 12 scale racing?

1 cell LiPo or 4 cell nimh? I run 1cell LiPo and have only been able to get the 312 to work in 17.5 motors, 323 or 312 with 13.5 motors. The newest 'stock' software does not work with 1 cell even when you turn off the 'bat protection'.

TryHard seems to be having good luck with 4 cell nimh with the 107 and 110? He described his results back a couple pages....

Hi All, Would any one know the optimal temperature range for the "Competition 3.0 - 17.5R"? I installed the new stock software over the weekend and was getting temps around the 85C mark. This was running without a heat sink or fan. Which I'm going to install for next meeting. But if someone says that the temp is fine then I wont bother.

Thanks in Advance.

Can someone suggest a starting roll-out for my SP Competition 3.0 10.5R in 1s World GT? Track would probably be described as a regular size carpet track. Oh yeah, speedo is a regular old sphere TC spec. Thanks

Cheers
Daniel

all of the sensors in the V3 motors are the same

thanx

ps: 4.8 final drive in a small track like that?

I used 4.8 final drive with the original or novak type 13.5 motor on a 40x100 footer track...not a problem, with very good speed.

Here is the thing you need to try.....your 7.7 final is WAY OFF...try 4.8 with your motor timing (the timing on your phyical motor) set to the middle...then keep gearing up untill you like the speed. I know the V3 13.5 ran alot cooler then any other 13.5 so gearing up is not a problem.

But if your track is REALLY tight (you never say how small is your track...) gearing up does not makes your any faster...you need punch and corner speeds....

I would say GEAR DOWN.....80C is probably what I would stop gearing up and 75C is probabbly what I would prefer to run.

That is a on the HOT side.
I would suggest dropping a few teeth or look at reducing some timing.
I wouldnt go higher than 70deg and for me my motors run nothing higher than 65 deg.

quick question, does the gt2.0 lpf come with a programmer? i recieved mine today w/o one :mad:
